To /ZZ whom. may concern be it known that I, SERN l?. l/Vniur, a citibustible and air to he thoroughly comunic-- gled White under the iutiuenee of heat` thereby rendering` the explosive mixture peculiarlv eiiicient when drawn intothe engine cylinder and With an economical consumption of power agent,

illitln these ends in vie-iv, the invention consists in the. novel construction and ar-- rangement of parte, as will be hereinafter described and claimed.

In the accompanying illustrate an embodiment of the invention, Figure .l is a vertical transverse Sectional vieW,.and Fig. 2 isa section taken on broken line 2-2 of Fig. l(

rlie reference numeral .5 designates a casingf comprising an inner Shell 6 and an outer sliel 7 which are spaced apart to afford tuin such as hot Water or the combusrcducts exhausted from an engine. nil outlet openings and l0 are proie top and bottoni ot said coinr the supply and Withdrawal of medium. i inner shell formed to 'furnish l. ally cylindrical chamber 11 which s with an induction conduit 1Q ang-ed tangentially with respect The. circular Wall til of is tiroltinged into said conduit, "i a dedector ii and pro- .roat ti/7,1 at the juncture the cylinder. This conom louter end with the opening-'oit inrete/i'. idelivery F lly of said chamber t. nt a uip''rie "m which pro- LU I .and coextensive extending through feeling provided Stien ivitli a suyc'ine cylinder.

i rehct'iveen a compartment 8 fora heating` drawings, which Near the top ot the rllie wall of the shell 6 opposite to the nipple 131 iS preferably formed with protuoerance le which is disposed in axial alincrnent with the nipple and serves as a pivot about which @o the gases are directed into the nippie,

lu operation, the combustible mixture is drawn through the induction Conduit 1Q, chamber 1l and deliver;v1 conduit 13 by the suction strokes of thev en ine, and in itspassuch mixturel injiirges against the surface ay of the dctlecttr 62 and is thereby caused to tioiv with great rapidity through the relatively small. throat 121 and sweep against the inner peripheral surface L oi' the chamber, resulting in the mixture taking a circular course or a Succession ot such' courses, about the nipple 131 and during which the vaporized portion is drawn from the center of the whirling body of uid into tlie'nipple to accomplish the uiost intimate connningling of the' explosive fluids which are delivered. into the nipple.

ln the flow-ot the fluids through the cham-y ber, the inherent centrifugal "torce drives any liquid particles against the chamber sur- Jface o to cause auch particles to be either broken by impact oi' dissipated by contactinrr with the relatively hot Wall Surface and rendering the atoniized or vapoiized liquid in suitable condition to he absorbed, as it were, by the ciurent or successive currents of gases which course about the nipple and which is subsequently drawn into the nipple in a gaseous condition.

lili/That l claim isl l, it fie-vice ot the character described, comprising a casing provided with a, circular chamber, a nipple extendingr axially thereinto and serving as the tei-iniziai of a deliver)r conduit, a protuberance disposed in axial alinenient with respect to said nipple, an induction conduit arranged in tangential relations' to' said cliainner, and heating compartment provided inthe casing` and iuclosingI said chamber and the conduits.

2. Si deviceot the character described, comprising a, casing 1provided with ein cular chamber, a nipple extending axially`A thereinto and serving as time terminal of a 05 deliver)7 conduit, an induction conduit ar, ranged in tangential relations to said chamber and connected therewith through a throat. of area than that of the conduit, and a heating` compartment provided in the casing' and inclosi'ng said chamber and the conduits.

3. A device ofthe character described, comprising a casing provided with a cir cular chamber, a nipple extending axially thereinto and serving as the terminal of a delivery conduit, alprotuberance disposed in axialalinement with respect to said nipple, an induction conduit arranged in tangential relations to said chamber and connected therewith through a throat of less area than that of the conduit, and a heating compartment provided in the casing and inclosing said chamber and the conduits.

4t. In a device of the character described, a circular chamber, a delivery conduit communicating with lthe chamber in axial relations thereto, an induction conduit connected tangentially with the chamber, and a detiector projecting int-o the induction. conduit to provide a contracted passage `between said induction conduit and the chamber so as to direct the gases against the peripheral Wall of the latter.l l

5. In a device of the character described, a circular chamber, a delivery conduit communicating With the chamber in axial relations thereto, a protuberance extending from the Wall of the chamber opposite to the intake end of said conduit, an induction conduit connected tangentially with the chamber, and a deiector projecting into the induction conduit to provide a contracted passage between said induction conduit and the chamber so as to direct the gases against the peripheral Wall of the latter.

6. A. device ot' the character described, comprising a casing having inner and outer shells, said inner shell being arranged to atford a chamber, and induction and delivery conduits respectively connected with the chamber in tangential and axial relations, said delivery conduit being of sufficient length to extend a distance into said chamber, and a heating compartment intermediate the casing shells andl provided-With inlet and outlet openings for the admission and discharge of a heating agent.

7. A device of the character described, comprising a casing provided with a cir cular chamber, a nipple extending axially thereinto and serving` as the terminal of a delivery conduit, and an induction conduit arranged in tangential relations to said chamber.
